1. Introduction to Edge AI

Traditional IoT architectures rely on the cloud. Microcontrollers gather inputs (temperatures, vibrations, or frames) and stream them back to centralized databases for processing. However, this structure demands high network bandwidth.

"By moving neural networks down to the microcontrollers themselves, edge architectures achieve sub-millisecond diagnosis and trigger relays instantly."

2. Neural Networks at the Edge

Modern microcontrollers like ESP32 now support TensorFlow Lite runtimes. Developers write predictive algorithms, convert them to lightweight flatbuffer models, and flash them onto local ROM clusters.
